IV Medicine Administration:
Infection Control
September 2009
Learning outcomes
• Explain the chain of infection and standard
precautions.
• To understand the application of the chain of
infection and standard precautions in relation
to IV therapy.
• Discuss the actions required to
prevent/minimise the risk of infection in a
patient receiving IV drug/fluid therapy.

Reservoirs
• Patients Skin – resident microflora
• Environment
• Equipment
• IV Solutions & drugs
• HCW Hands -Transient microflora
February 2009
5
Means of Exit
• Secretions such as bodily fluids e.g.
blood
• Skin such as skin scales
February 2009
6
Route of Transmission
• Direct contact - on healthcare workers hands
• Indirect contact- contaminated equipment,
fluids, parenteral drugs or infusates
• Puncture of skin (inoculation / blood borne)

The minimal level of infection
control precautions that apply in
all situations.

Preparation
• Clean Work Surface
• Hand
Decontamination
• Reconstitution
• Patient Preparationexplanation/skin
• Venous access

Remember if you are interrupted you need to
decontaminate your hands again

Administration
Additive/solutions
Always check:
•
•
•
•
Packaging Intact
Expiry date
Particulate Matter
Glass for cracks
Bolus/flushes
Always:
•
•
Clean the port
thoroughly
Where possible use
needle free connector

Detection of Infection
Infection can present in
a number of ways:
• Local Site Infection
• Microbial Phlebitis
• Systemic Infection
February 2009
14
Inspection
At set Intervals, inspect for signs of
local infection & phlebitis:
1.
2.
3.
4.
5.
Tenderness
Erythema
Swelling
Purulent Discharge
Palpable Venous cord
February 2009
15
Suspected Cannula Infection/
Phlebitis
Local • Stop infusion
• Swab site if discharge visible
• Vascular access device - send tip to microbiology for
culture.
• Inform medics
• Document all observations and interventions
Systemic - as above
• Vital Signs observations
• Inform medics
• Document all observations and interventions
Treatment dependent on individual, presentation and16
causative organisms isolated

Phlebitis Scale (Jackson 1998)
IV site appears healthy
0
One of the following is evident:
•Slight pain near IV site
OR
•Slight redness near IV site
1
TWO of the following signs are evident:
•Pain at IV site
•Erythema
•Swelling
22
ALL of the following signs are evident:
•Pain along path of cannula
•Erythema
•Induration
ALL of the following signs are
evident & extensive:
•Pain along path of cannula
•Erythema & Induration
•Palpable Venous Cord
ALL of the following signs are evident
& extensive:
•Pain along path of cannula
•Erythema
& Induration

No Signs of Phlebitis
OBSERVE CANNULA
Possibly first signs of Phlebitis

Giving sets
• Change giving set after administration
of blood or blood products either every
12 hours or when the transfusion is
complete
• After 24 hours of TPN administration
• After 72 hours if clear fluids are used
• All ward prepared infusions should be
changed after 24 hours
February 2009

Infusate Sepsis
10 hours after infusion 3
commenced patient spiked a
temp.
Patient pulled out cannula.
Cannula resited same
infusion recommenced.
Temp spiked again, blood
cultures taken.
Environmental
Pseudomonas sp isolated
from blood.
February 2009

Treatment
•
•
•
•
Stop the infusion - inform medical staff
Send blood cultures & swab from site
Monitor vital signs
Remove the line - send tip to
microbiology for culture

Dressings
Function of the dressing is:
• To protect the site of venous access
• To stabilise the catheter in place
• Prevent mechanical damage
• Keep site clean
February 2009
21
Documentation
• Document all IV sites 12 hourly (once per
shift)
• Nursing Notes
• Patient Care Plans
• Documentation is evidence that assessment
has been carried out
February 2009
22
Key Points
• Intravenous drug administration if not done
properly can cause infection
• Hand hygiene, aseptic technique, correct
preparation and administration of iv drugs /
solutions and line changes will minimise the risk
of infection
• Holistic assessment of the patient and
monitored as required to meet individual needs
as per local policies using assessment tools
(MEWS/SEWS)
• Accurate documentation is essential
